Storing Cut Alfalfa Hay

We are planning on cutting our next season's crop of alfalfa with a feed
cutter and storing it in a barn for winter feeding.

The hay must, of course, be thoroughly cured, because of the great
danger of heating in a tight mass. A. Balfour says: "I have been cutting
alfalfa into a barn for wo seasons. It is absolutely necessary to have
the sides and floor tight, and it is easier to feed it if it is in a
loft. The hay is best stacked first, and must be thoroughly cured."
